COMBINED HELMET AND FACE-PROTECTOR- Specification of Letters Patent.

Patented. April 3, 1906.

Application filed July 17. 1905 Serial No. 270,093.

To all whom it may concern.-

Be it known that I, SAMUEL JOHN LAVIS, of the town of Bowmanville, inthe county of Durham, in the Province of Ontario, Canada, have inventedcertain new and useful Improvements in a Combined Helmet and-Face-Protector, ofwhich the following is the specification.

My invention relates to improvements in a combined helmet andface-protector; and the object of the invention is to devise a simple,strong, durable, and efficient protection for the head and faceparticularly adapted for the use of firemen and others subjected to thedangers of smoke, fumes, heat, fire, and the like; and it consists,essentially, in the features, combination, and arrangement of partshereinafter described, and particularly set forth in the claims.

Figure 1 is a perspective view of my helmet, showin the method ofadjustin it on the head. ig. 2 is a cross-sectiona view through thecenter of the nose piece and tank.

In the drawings like letters of reference indicate corresponding partsin each figure.

A is the crown.

B is the tank, and C is a channel of rubber or like material leadingfrom the said tank to the nose-piece D.

E is a spark or water shield attached to the rear of the helmet by ahook and eye or other similar device.

F is the face-piece, connected to the crown by hinges G G, and H is astrap securely fastened to the rear of the crown and suitably adjustably connected to the face-piece F.

M represents the eyeholes, with mica or other suitable diaphanouseyepieces M held lseicurely to the face-piece by screws M or the C is aspiral-spring covering for the channel O, thereby protecting it from thedestroying influences of heat, flame, and the like, at the same time suplying a hard, strong, durable, and flexib le outer covering for thechannel.

D D are s onges within the combined nose and mout piece D, held apart byrods D which allow the fluid from the tank to flow down and well overthe surface of the sponges, respectively.

L is a covering for the nose'and mouth piece, held thereto by means ofthe hooked ds of the handle or rod L and L is a slidshutter providedwith portions N, projectin outwardly through the outer covering L an bymeans of which the shutter is moved.

L represents openings in the shutter, which correspond when the shutteris in its upper position to the holes L in the outer covering andprovide means for regulating the airsupp y in accordance with the stateof the surrounding media.

I is a'shutter on the side of the nose and mouth piece D, free to slidein guideways P, and allows direct passage of air to the o erator. Thusit is seen that avery fine ad iuStment of the air-passage to theoperator is easily obtainable by means of shutters provided on the frontand the sides of the nose.

R is a suitable adjustable air-valve allowing atmospheric pressure intothe tank, thus causing the fluid therein to flow more easily whenrequired. 'An 0 ening A with a cap or covering is supplie in the crown,through which the liquid is poured into the tank B. The inner surface ofthe helmet is covered with a felt lining ,T or the like, which servesfurther to protect the wearer from extremes of heat and also forms apadding for the face and head.

A suitable handleA is attached, whereby the helmet may be convenientlycarried.

To those more directly subjected to flame ear-protectors may be sup liedextending from the face-piece, which a though not impcding sound willamply fulfil the purpose ior which they are designed.

WVith such a combined helmet and faceprotector as I have hereindescribed it will be seen that an important advancement has been made inregard to the method of protection in the form of head-gearing for thosesubj ected to such forms of danger and a long-felt want finally andsuccessfully overcome.

What I claim as my invention is 1. In a combined helmet andface-protector, the combination with a crown, of a tank in the upperportion thereof, a face-piece hinged to said crown, having suitableeyeholes therein, an inner channel connecting said tank to thenose-piece, an outer flexible spiral-spring covering for said channel,and means for admitting and regulating the airsupply to the wearer asand for the purpose specified. I

2. In a combined helmet and'facerote'ctor, the combination with thecrown avin a tank therein, of a face-piece hinged to sai d crown, andhaving suitable eyeholes therein,

a suitably-formed nose-piece on said facepiece, a perforated coveringfor the nosepiece, a correspondinglyerforated shutter sliding under andwithin t e covering, means for manipulating said sliding shutter, and aflexible channel connecting the tank to the noseiece as and for thepurpose specified.

3. n a combined helmet and face-protector, the combination with thecrown portion having a tank therein, of a faceieoe hinged to said crown,and having suita le eyeholes therein, a suitably-formed nose-piece onsaid face-piece, a perforated covering for the nosepiece, acorrespondinglyerforated shutter sliding under and within t e covering,means for manipulating said sliding shutter and supplemental air-valveson the sides of the nose-piece as and for the purpose specified.

4. In a combined helmet and face-protector, the combination with thecrown portion, of a tank secured therein, a faceiece hinged to saidcrown; a flexible channe connecting the tank to the nose-piece of saidface-piece, means for admitting and regulating the air supply to thewearer and rods fastened with specified.
